Subject: [PATCH] scripts: check.c fix compile error

Fix the following compile error:

checks.c: In function ‘check_simple_bus_reg’:
checks.c:876:41: error: format ‘%lx’ expects argument of type
‘long unsigned int’, but argument 4 has type ‘uint64_t {aka
long long unsigned int}’ [-Werror=format=]
  snprintf(unit_addr, sizeof(unit_addr), "%lx", reg);
                                         ^
checks.c:876:41: error: format ‘%lx’ expects argument of type
‘long unsigned int’, but argument 4 has type ‘uint64_t
{aka long long unsigned int}’ [-Werror=format=]
cc1: all warnings being treated as errors
Makefile:304: recipe for target 'checks.o' failed
make: *** [checks.o] Error 1
